In th nature of this forum looking to the future for conflict possibilities I propose the following story from New Scientist. In all of history the things that could cause bitter war have always seemed to be food and religion. If you're hungry and starving you have nothing to lose (and it naturally balances population numbers!).
Recently at a DHS briefing they talked about something called mono-culture, or the fact that all wheat is basically the same strain and could be taken out by a simple blight (thereby killing a lot of people).
The story is located here (http://environment.newscientist.com/channel/earth/mg19425983.700-billions-at-risk-from-wheat-superblight.html) and selected quotation follows.
Billions at risk from wheat super-blight
"This thing has immense potential for social and human destruction." Startling words - but spoken by the father of the Green Revolution, Nobel laureate Norman Borlaug, they are not easily dismissed.
An infection is coming, and almost no one has heard about it. This infection isn't going to give you flu, or TB. In fact, it isn't interested in you at all. It is after the wheat plants that feed more people than any other single food source on the planet. And because of cutbacks in international research, we aren't prepared. The famines that were banished by the advent of disease-resistant crops in the Green Revolution of the 1960s could return, Borlaug told New Scientist.
The disease is Ug99, a virulent strain of black stem rust fungus (Puccinia graminis), discovered in Uganda in 1999. Since the Green Revolution, farmers everywhere have grown wheat varieties that resist stem rust, but Ug99 has evolved to take advantage of those varieties, and almost no wheat crops anywhere are resistant to it.
The strain has spread slowly across east Africa, but in January this year spores blew across to Yemen, and north into Sudan (see Map). Scientists who have tracked similar airborne spores in this part of the world say it will now blow into Egypt, Turkey and the Middle East, and on to India, lands where a billion people depend on wheat.
There is hope: this week scientists are assessing the first Ug99-resistant varieties of wheat that might be used for crops. However, it will take another five to eight years to breed up enough seed to plant all our wheat fields.
The threat couldn't have come at a worse time. Consumption has outstripped production in six of the last seven years, and stocks are at their lowest since 1972. Wheat prices jumped 14 per cent last year.
Black stem rust itself is nothing new. It has been a major blight on wheat production since the rise of agriculture, and the Romans even prayed to a stem rust god, Robigus. It can reduce a field of ripening grain to a dead, tangled mass, and vast outbreaks regularly used to rip through wheat regions. The last to hit the North American breadbasket, in 1954, wiped out 40 per cent of the crop. In the cold war both the US and the Soviet Union stockpiled stem rust spores as a biological weapon.
After the 1954 epidemic, Borlaug began work in Mexico on developing wheat that resisted stem rust. The project grew into the International Maize and Wheat Improvement Center, known by its Spanish acronym CIMMYT. The rust-resistant, high-yielding wheat it developed banished chronic hunger in much of the world, ended stem rust outbreaks, and won Borlaug the Nobel peace prize in 1970.
